rh'therapeutic appliance in accordance with this invention includes anadjustable lampsufppoi ting standard, a flexible hanger,

carried by the hanger, a directing element for the light rays, and 'abase for 'the standard. v p

The adjustable supporting standard is of thetelescopic type comprises alower I tubular s'ection l and an upper tubular 'section 2, whichextends in the upper end of the section 1 and further is verti'callyadjustable relative to the said section 1. The supporting standard isconstructed of any suitable in'etallic material, f i t The sectionl isprov ded at itsjup pf eiid .withPQrip h e d 3 M d it t bite end with Y areduced peripherally threaded 'terininal"port ion 4, and ajbove thelatter carries an adjustable threaded collar 5. I ,,,Th ndar lcOi iec dto ws lp- Ported by a eba'se'consistiiig of ahollow'hody portion said acover 7 therefor, and each of which is fbrr'ned from metallic material,and 'Witht'he body portitinfi of materially greater weight thantheeoverZ, and further with the. latter conforming in contour to andsnugly fittingthe outer face of the body portion 6,

The base isopeini at jits bottom and has a closed top flattenedcentrally thereotas at 28. I. The base preferably s, circular incontour, but it is to be understood that it, can be of any shapedesired." v c The body portion, 6, centrally ofits top is formedwithanopening 9 havingits wall threaded, and said cover 7,, centrally;thereof is providedv with an opening 10, isters with the open'ingQ,

, The reduced lower terminal portion is i which reg- .exte'nded through:the openin g 1'0 and has threaded engagement with the wallof the opening9 whereby said section 1 is secured in an upright position bythebase.The collar5 is adjusted downwardly in the section 1 to engage theflattened portion 8, of the base,

so that the cover 7 will be tightly clamped tothe body portion 6;

f The section 2 of the standard, at upper end is provided withperipheral threads 11, and said section 2 has its lower terminal portion12 provided with a pair of diametrically opposed insets 13, forming apair of lengthwise extending grooves 14; opening at their lower ends atthe inner end edge of said section 2 At tht upper end of each oithe-greoves '14, the section 2 is formed with an opening 15, for thepurpose of pivot-ally conn'ecting to the section 2 21 dependingresilient trictional clamp formed from a single length of spring wire.

The frictional clamp comprises a pair of side portions each having anoutwardly inclined upper part 16 ot substantial length, and an inwardlyinclined lower part 1?, preferably of greater length than the upperpart. The upper part in oi one side portion extends in an oppositedirection with respect to the upper-part 16 the other side portion. Thelower parts 1? of said side portions not only extend in 'ardly at aninclination towards each other, but i ur ther extend outwadly at anangle with re spect to the direction in which the upper parts 16 extend.

The frictional clamp further includes a top formed of a pair orextensions 18, 19 and each thereof extends inwardly at an angle withrespect to the upper end of the f upper part 16 ot' a side portion. Thee tensions 18, 19 are disposed at an inclination so that they willoppose eaclrother. The extensions 18 and 19 are inounted in the section2 of the standard, extend in opposite directions with respect to eachother and each projects inwardly through an opening 15. By thisarrangement the frictional clamp is pivotally connected to and suspendedtroni the section The frictional clan'ip further includes a bottomformed of a pair of semicircular portions 20. 21 and each of which isdisposed at right angles to the lower end o1 a lower part 1.7. Theportions 20, 21 are so disposed whereby one will be oli set with respectto the other when the clamp is set up as shown in Figure 3.

The frictional clamp further includes a coupling portion formed of acoiled upper part 22 and a pair of oppositely extending dependingvertical extensions 23, 24:, oppose the lower parts 17 oi? the sideportions. The extension 23 terminates in the curved portion 20 ot thebottom and the extension 24- terininatcs in the curved portion 21 oi thebottom. The coupling member normally maintains the side portions andbottom extended and acts to set up a frictional clamping action betweenthe bottom of the clamp and inner tace oi the section 1, of the standardat two points.

The upper parts to of the end portions are of greater length than thelength of the which grooves .l-"l, and the side "alls of these latterlimit the shitting movement of the side portions. The grooves i i alsoprovide clearances for the side portions 01' the clamp so that thesection of the standard can be rted into the section thereof.

Tle outer diameter the section 2, with espect to the inner diameter ofthe section 1, is such as to provide a snug sliding iit ietween saidsections, and after he section has been Vertically adjusted, the i sictional clamp engaging w th the section 1, will hold the section 2 inthe position to which it has been adjusted;

Detachahly engaging of the section 1, an n l {3 5 meta an inerniediateflexible portion 3;). of substanial length and which is fixedlyconnected if) t 10 sleeve 26 and 2?.

l crposed bet-ween the flexible hanger the section 2 ot the standard, isa i and couplin member tor connecting the hanger to said section 2, answhich further provides "for the entrance of the circuit connections 31which extend through the hanger to the lamp 32. The coupling memberconsists of a hollow semi-spherical body 33, having an opening for theentrance thereto 01 the circuit connections 31;

integral with and depending troin the body portion 33 is an interiorlythreaded collar 35, for engagement with the threads 11. Formed integralwith the top of and depending within the body portion 33, is aninteriorly threaded collar 36 which is engaged by the reduced threadedlower end 29 ot the sleeve 28. When the coupling member is secured tothe hanger and section 2, the sleeve 28 abuts against the outer face ofthe top of the body portion 33, which'is flattened at such point, as at37.

The reduced upper end 27, of the sleeve 26, detachably engages with thesocket of .the lamp 32, whereby the latter will he suspended from theupper end ot the hanger and can be adjusted to any desired angularposition with respect to the standard:

iilounted on the socket of the lamp 32 and inclosing and depending "fromthe globe oi the lamp is a directing element for the light rays, andwhich is in the form ot a hood cointructed from a single sheet of thinmetallic material highly polished on its innor and its outer face.- Thehood is circular in contour and includes a flaring lower portion 38 ofcompound curvature in vertical section and which is outwardly beaded atits bottom, as at 39. The hood further includes a trusto-conicalintermediate portion e into which merges the top of the lower portion38. The upper circular portion of the hood is indicated at 41, and intowhich merges the top of the intermediate portion. The upper portion 41is formed at its top with an inwardly extending apertured annular flanget2 providing means for connecting and suspending the hood from thesocket ofthe lamp. The intermediate portion is of lamp, with thedirecting element, to be positioned at any desired height, and theflexible intermediate portion of the hanger allows for the lamp anddirecting element to be set at any suitable inclination so that thelight rays from the lamp can be directed at any desired point upon thepatient without any inconvenience.

It is thought that the many advantages of a therapeutic appliance, inaccordance with this invention can be readily understood, andalthoughthe preferred embodiment ofthe invention is as illustrated anddescribed, yet it is to be understood that changes in the detailsotconstruction can be had which will fall within the Scope of theinvention as claimed.

VVha-t I claim is:

An adjustable support comprising abase, a sectional standard connectedtherewith and formed of an adjustable tubular upper section and astationary tubular lower section, said upper section telescoping in saidlower section and having its lower terminal portion provided withlengthwise extending diametrically opposed peripheral grooves and acontractile frictional clamp providec with right angularly disposedupper ends extending in and pivotally connected to said upper section,said clamp depending from and seating in the grooves of said uppersection and further frictionally engaging with the lower section tomaintain said upper section in adjusted position.

In testimony whereof, I afiix my signature hereto.
